Core network interface for packet domain for UMA UNC applications

摘要

An UMA network controller is dedicated for an UMA mobile network including a CS core network and a PS core network with a SGSN. The UMA network controller includes a security gateway and a control means coupled to one another. The security gateway is arranged i) to ensure security procedures between mobile stations and the UMA world, ii) to forward messages relative to the control plane for the packet switched core network between mobile stations and the control means, and iii) to forward messages relative to the user plane for the packet switched core network between mobile stations and the a serving GPRS support node. The control means is intercalated between the security gateway and the serving GPRS support node and arranged for handling the control plane for the packet switched core network.

1. An UMA network controller for an UMA mobile communication network comprising a circuit switched core network and a packet switched core network with at least one serving GPRS support node, the UMA network controller comprising:
a security gateway; and a controller coupled to said security gateway; said security gateway being arranged to:
ensure security procedures between mobile stations and an UMA world;forward messages relative to a control plane for said packet switched core network between mobile stations and said controller; andforward messages relative to a user plane for the packet switched core network between mobile stations and said serving GPRS support node via a Gb+-2 interface;wherein said controller is intercalated between said security gateway and said serving GPRS support node via a Gb+-1 interface, said controller is arranged for handling the control plane for the packet switched core network, and said controller is arranged to exchange information elements, via the Gb+-1 interface, relative to an IP address and a communication port number of a mobile station and to an IP address and communication port number of said serving GPRS support node, with said serving GPRS node.
